[andy3]

Hey guys,
New member here....I stumbled onto the site a couple hours ago because I just (2 hrs) ago got this message as i was editing photos on my mbp 15inch. 2012 (not sure f it matters but just in case.

Mac OS X can’t repair the disk “Andrew's Drive.”

You can still open or copy files on the disk, but you can’t save changes to files on the disk.

Now i've owned this laptop for about 6 months max, so I don't know much as far as trouble shooting goes, but I have seen people have had this issue and had if fixed and I'm hoping I can be one of those guys. I have about 400+ gigs of pictures and videos (mostly videos, I'm a student film maker and I really , really would not like to lose any of my files). Now, utilities says nothing wrong, it verifies and repairs, but on the first folder ( seagate goflex 1tera in utilities), but the second folder (mount point i'm guessing to the right Andrews drive says it key are out of order. Is there anything I can do to get this working again.... I see some success with terminal (i not too versed on this also but i can cooperate well and follow directions if given, can some one please help?

First thing to do is get your terms right. It appears you have a 1Tb seagate - is it an external or internal drive? Is it your boot volume?

Since it's this year's Mac, you have a recovery partition built in. I suggest you restart the computer, hold down the Option key at the startup chime, and wait for the boot menu to appear.

Choose "Disk Utility", and run "Repair disk" on everything.

If Disk Utility can't fix the volume, you have 3 choices:

- Purchase a high-powered repai program like Disk Warrior
- Copy the contents to another drive, reformat and restore
- Reformat the drive and recover from a backup.

(you do have a backup, right?)

The reformat and restore options are usually much fast er than Disk Warrior. Great software, but it's famously slow. Plan on a 24-hour repair run.

Extensive writing and rewriting has been known to mess up a drive. Film making will do that.

There's a step accidentally missing there. Right before choosing Disk Utility, you'll need to select the Recovery partition from the available bootable disks.

That would help, wouldn't it?
